If this is a high performance build, A pinion spacer & shims should be used in place of the crush sleeve on GM corporate diffs.

10 inch pounds isn't the end of the world, I'm guessing this is with a seal? Try seating the bearing & races if you haven't already, A few taps on the back of the pinion, & a few taps the the yoke with a brass drift will do. Recheck rotational torque. (Rotate pinion between taps)

If it's still at 35 in. lbs., It will run there! Just be easy on the break-in....Drive around the block, Park the truck & let it cool 30 minutes, Repeat 4 or 5 times.

If you just not happy because the specs, Replace the sleeve & try again, I wouldn't recommend un-crushing on a fresh build.

Cline. I'm working on a 12 bolt. Also adding a Detroit truetrac along with the gears. So your thinking I should do away with the crush sleeve and go with the spacer and shims? I'll have to look into that. Thank you OK got a set coming from Ratech. says to start with spacer and 3 shims, torque nut to 125 Ft.lbs. check preload (25 in. lbs.?)

The specs I have are the same as Ironangel's (Yukon Gear & Axle specs), I don't know where my factory service manual is right now......But generally the factory rotational torque spec are higher to go along with different break-in procedures.

20-25 in. lbs. is OK on any Corporate differential except a 7.5" (less) or a 10.5" (more), Bigger Dana diffs can call for up to 55 in. lbs.!!
